Described as a "real gem" in the Scottish business world, Wood Mackenzie's impressive growth and strategy won the judges' vote.

The consulting company, which specialises in the energy, mining and metals industries, was praised for its "very strong board", its approach to staff development and the success of expansion both through highly-targeted acquisitions and organic growth.

The worldwide expansion of international architectural practice RMJM also impressed the panel. Its merger with US-based Hillier has taken the company into a different league and strengthened its position in many of the world's fastest-growing markets.

Loganair, which provides regional air services throughout the Highlands & Islands, was also praised for a "creditable performance" in a rapidly changing marketplace..
